Equivalent & Substitute Parts for M22-2531905

Part Overview

The M22-2531905 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board applications. This 19-position connector operates at 2.00mm pitch with male pin contacts and solder termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and component procurement.

Substitute Part Grouping Explanation

The M22-2532005 is identified as the manufacturer-recommended substitute for the M22-2531905. Substitution eligibility is determined by the following critical parameters that must remain consistent:

• Series: M22 (same connector family)
• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Length - Mating: 0.138" (4.60mm)
• Contact Length - Post: 0.094" (2.40mm)
• Insulation Height: 0.079" (2.00mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Polyamide (PA6T), Nylon 6T
• Operating Temperature: -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Current Rating: 1A per Contact
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The primary difference between the main part and substitute is the number of positions: M22-2531905 provides 19 positions, while M22-2532005 provides 20 positions. This difference reflects the cuttable header design of the M22 series, allowing the 20-position variant to serve applications requiring 19 or fewer positions through mechanical trimming.

Parameter Comparison

Engineering Selection Recommendations

The M22-2532005 is the active production equivalent for the obsolete M22-2531905. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including pitch, contact geometry, termination method, and thermal operating range. Both parts comply with ROHS3 and REACH requirements, ensuring regulatory alignment for current applications.

The M22-2532005 offers the advantage of active product status with higher inventory availability (3002 pieces in stock versus 893 pieces for the obsolete variant). The 20-position configuration of the substitute accommodates the 19-position requirement through the cuttable header design inherent to the M22 series, allowing mechanical trimming to the exact position count needed.

Frequently Asked Questions (FAQ)

Q: Can M22-2532005 directly replace M22-2531905 in existing designs?

A: Yes. The M22-2532005 maintains identical electrical and mechanical characteristics across all critical parameters. The 20-position header can be trimmed to 19 positions using standard mechanical cutting methods appropriate for cuttable header connectors.

Q: What is the difference between the 19-position and 20-position variants?

A: The M22 series connectors are designed as cuttable headers. The M22-2532005 (20-position) provides one additional position compared to the M22-2531905 (19-position). Applications requiring exactly 19 positions can use the 20-position variant with the final position mechanically removed.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the current rating for each contact?

A: Both connectors are rated at 1A per contact, with an operating temperature range of -40°C to 105°C.

Q: Why is M22-2531905 listed as obsolete?

A: The M22-2532005 serves as the active production part for this connector family. Harwin Inc. recommends the 20-position variant as the standard offering, with the cuttable design accommodating various position requirements.
